CHARLES B. MAXSON, OF \VESTERLY, RHODE ISLAND.

SHEET-DELIVERY FOR PRlNTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 458,059, dated August 18, 1891.

Application filed May 2, 1891. Serial No. 391,392. (No model.)

To all whomit may concern:

Be it known that I, CHARLES B. MAXSON, a citizen of the United States, residing at WVesterly, in the county of IVashington and State of Rhode Island, have invented new and useful Improvements in Sheet-Delivery for Printing-Presses, of which the following is a specification.

This invention relates to an improvement in sheet-delivery for printing-presses; and the invention consists in the details of construction set forth in the following specification and claims, and illustrated in the annexed drawings, in which-- Figure 1 is a side elevation of the sheetdelivery. Fig; 2 is arear view of Fig. 1; and Fig. 3 is a detail sectional view taken on the line x 00, Fig. 2.

In the drawings, the letter A indicates the frame of the machine, having a feed-board B, from which the sheets are fed to the impression-cylinder O to be printed by the type-bed D. The printed sheet is taken off the impression-cylinder by the delivery-cylinder E, and said sheet passes thence between the fingers F G,'by which it is guided between the delivery-rollers H I.

The cylinder E and rollers H I are each shown in the drawings, Fig. 2, as consisting of a series of disks. The fingers G extend partly about roller H. The shafts of rollers H Iare mounted in a frame K, and the shaft of roller H has gear-wheels L, traveling along racks M.

A link N connects the frame K with an arm of lever O O, fulcrumed at P, and connected by link Q with a crank or pin R on the shafts of theimpression-cylinder. \Vhen a sheet isv fed between the fingers F G and the edge of the paper enters between rollers H I and said rollers are moved away from the cylinder E, the roller 11 is rotated by the gearwheels L, and the roller I is rotated by frictional contact with the roller H, so that the sheet is fed out between rollers HI and transferred onto the receiving-table T.

The frame K has guide-rollers U, suitably flanged to travel and remain on the tracks V. One corner of the table T is held up by arm \V. This arm supports one corner of the table and at the same time allows room and free swing to lever O O.

The pins X trip the grippers on cylinders C E and the gears Y transfer motion between said cylinders and between the impressioncylinder and the type-bed.

The delivery-rollers H I, it is noticed, are moved positively back and forth, and the motion of said delivery-rollers is independent from the motion of the delivery-cylinder E, said cylinder having a rotary motion, while the rollers H I travel back and forth. It will be noticed that the guide-fingers F alone would guide or slide the sheet in between rollers H I, but it is preferable to have two sets of fingersF Gr.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with an impressioncylinder, a delivery-cylinder, and a receivingtable, of horizontally-reciprocating deliveryrollers for receiving the printed sheet from the delivery-cylinder and transferring it to the table, a suitable track or way'for said deliveryrollers, means, substantially as described, for reciprocating the delivery-rollers,

and guiding means, substantially as described, for guiding the sheet from the delivcry-cylinder to the delivery-rollers, substantially as described.

2. The combination, with an impressioncylinder, a delivery-cylinder, and a receivingtable, of horizontally-reciprooating deliveryrollers for receiving the printed sheet from the delivery-cylinder and transferring it to the table, means, substantially as described, for reciprocating the delivery-rollers, and guidefingers for guiding the sheet from the delivery-cylinder to the delivery-rollers, substantially as described.

3. The combination, with an impressioncylinder, a delivery-cylinder, and a receivingtable, of horizontally-reciprocating deliveryrollers for receiving the printed sheet from the delivery-cylinder and transferring it to the table, guiding means, substantially as described, for guiding the sheet from the delivery-cylinder to the delivery-rollers, and mechanism, substantially as described, for positively moving the delivery-rollers back and forth, substantially as described.

4:. The combination, with an impressioncylinder, a delivery-cylinder, and a receivingtable, of delivery-rollers for receiving the printed sheet from the delivery-cylinder and IOO transferring it to the table, a guide F, and guide-fingers made to extend from the delivery-cylinder partly about one of the deliveryrollers for guiding the sheet from said delivery-cylinder to said delivery-rollers, substantially as described.

5. The combination, with an impressioncylinder, a delivery-cylinder, and a receivingtable horizontally reciprocating, of deliveryrollers for receiving the printed sheet from the delivery-cylinder and transferring it to the table, and mechanism, substantially as described, for rotating the delivery-rollers independently of the delivery-cylinder, substantially as described.

6. The combination, with an impression cylinder, a delivery-cylinder, and areceivingtable, of delivery-rollers for receiving the printed sheet from the delivery-cylinder and transferring it to the table, one of said delivery-rollers being provided with a gear-Wheel, and a rack upon Which said gear-Wheel travels, guiding means, substantially as described, for passing the sheet from the delivery-cylinder to the delivery-rollers, and means, substantially as described, for traversing the delivery-r0llers, substantially as described.

7. The combination, with an impressioncy1inder,a delivery-cylinder and a receivingtable, of delivery-rollers for receiving the printed sheet from the delivery-cylinder and transferring it to the table, guide-rollers for said delivery-rollers, and suitable tracks for the guide-rollers, guiding means, substantially as described, for passing the sheet from the delivery-cylinder to the delivery-rollers, and means, substantially as described, for traversing the delivery-rollers, substantially as described. a
